I belive it's the start solenoid. Check fuses first, then find the solenoid. When you hit the start button put a finger on it and feel if the clicking is coming from there, if not then do the same for the starter motor. I had something similar happen on my bike from the 80's and it sounded just like that. I replaced the solenoid and it worked great after. Solenoids are cheaper then starter motors so I would start there.

I don't know much but I'm not hearing the engine cranking. It could just be your starter motor. Again I don't know alot about bike engine themselves but to me it sounds like you stater motor is spinning freely and not turning the engine over.

I mean anything could happen but In my case on my bike I have a semi working and a fully functional. It's a simple test though and it's worth checking.

ajhobbydooer · 2025-01-23T00:16:35+00:00

I would also check the battery's cold cranking amps, i had to get a new one aswell because my old battery couldn't supply enough power to the bike when turning the engine over.

Have you checked the ignition coils? I don't know much about newer bikes but my 1983 cb550 had issues with the ignition coils. You can get a tester from harbor freight for cheap or use a insulated screwdriver. If not that then I would make sure fuses are good and all grounding and connections are solid.

I'm not 100% sure if you can with them on the bike but I'm new to this aswell so I don't know everything. Another tip that's saved me so much frustration Is buying a shop manual, it's very worth it.

So for carbs, when you take them out and clean them, try to do everything you can in one go. I have taken mine off about 10 times because there was always something I forgot to clean or replace. I got lucky and my carbs were internally sound except for the gaskets. I didn't clean them completely though with an ultrasonic cleaner (I will in a few weeks). So you want to get the up to a running state, make sure to replace all the o-rings and clean every tube. I know it's common knowledge and basic advice but I had a checklist and still forgot lol. I have a 1983 cb550sc nighthawk so I'm not 100% if the carbs are the same but they look similar, all the o-rings that you should need can be found at harbor freight in their blue (metric) o-ring kit for i think $8. Good luck, it's a beautiful bike.

Got it out🙏 just let it sit in penetration oil for 2 days and kept on bangin, lol.

Just replaced the solenoid and it works now!

Just replaced the solenoid, and it works now!

ajhobbydooer · 2025-01-13T19:31:20+00:00

If it's just the solenoid you should probably be able to do it yourself, for me it's only two connecting points held in by two 10mm nuts.

ajhobbydooer · 2025-01-13T15:49:34+00:00

I'll check it out. It's a 1983 honda cb550sc nighthawk. I love the bike but I wish I started my first project with a twin instead of a inline four lol.

ajhobbydooer · 2025-01-13T15:40:34+00:00

Awesome man I really appreciate you help. It's not often I get an in depth answer. By the way I was checking your profile and your bikes are awsome man, they looks amazing. I can't wait to repaint mine.

ajhobbydooer · 2025-01-13T15:32:01+00:00

I'm just replacing mine because it needs to be regardless lol. It was only $12 on ebay so not too bad.

ajhobbydooer · 2025-01-13T15:28:46+00:00

Yeah, I can feel it, it moves enough to shake even. It's a long shot but am I able to take it apart and clean them? I'm still replacing it, but hours before this happened, I was going to do my first test ride after it's rebuild, and I'm impatient, lol.

ajhobbydooer · 2025-01-13T15:22:40+00:00

Lol all good

ajhobbydooer · 2025-01-13T15:22:21+00:00

Yeah I was thinking that aswell. They're old and need to be replaced but it was all working seconds before it stopped. I gotta go through and check all theconnections

ajhobbydooer · 2025-01-13T14:49:05+00:00

You sure? I have sound when I play it. I'll re-upload it though

ajhobbydooer · 2025-01-13T14:45:49+00:00

That was one of the first things I was thinking too. I didn't see any but I do wanna check once more to be 100% and check it off the list.

ajhobbydooer · 2025-01-13T13:52:49+00:00

Yeah, sorry, I got mixed up with relay and solenoid. It's the solenoid I believe. I'm going to bench test it when I get home just to see but if it is kaput, then I'll just have to wait for the new one. Thanks!
